Hi everyone, 

I'm working on a project involving pre- and post-training comparison of functional connectivity using CONN toolbox. I decided to script my analysis and I'm having some issues with it. Precisely, I had already preprocessed 3 subjects and decided to add 4 more, during the preprocessing of these new subjects the program got stuck and crashed. My question is: How can I finish preprocessing the 4 new subjects without risking to modify the already-existing subjects' files? 

My first guess would be to delete the new subjects' preprocessing steps that took place and simply re-run all the steps altogether; but, unfortunately in batch scripting I have no clue how to do it.

As now, my only guess is to create a new project for each subject and then merge the projects together using conn_merge() function. 

Any help would be sincerely appreciated :)

Hi Riccardo,

If your batch script is only running preprocessing (e.g. importing those 4 subjects' data was done either using a different script or from the GUI) then simply select in batch.subjects the subjects that you want to continue running preprocessing (e.g. the 4 new subjects), and select in batch.Setup.preprocessing.steps the remaining preprocessing steps (the step where it crashed last time and any steps after that). 

Best

Alfonso

Hi Alfonso,

Thank you so much for your reply, it has been of invaluable help! 

I have another question regarding how to make the analysis using conn_batch. Particularly, I do not know how I should create the batch if my subjects have already been preprocessed. Do I need to add particular files to it?

Thanks in advance
